Exercício de produção do alumínio
Exercício:
O alumínio é um metal muito importante na nossa sociedade moderna. A produção de metal alumínio (Al) a partir de seu óxido (Al2O3) presente nos minérios consome muita energia. A reciclagem do alumínio metálico gasta somente 5% as energia necessária para produzi-lo a partir do minério (óxido de alumínio).
Considerando que a quantidade de energia utilizada em todo processo de produção do alumínio a partir de minério é de 5000 kJ para cada 1 mol de alumínio metálico produzido.
Determine quanto de energia é poupada quando se recicla uma tonelada de metal de alumínio.

Hello, I enjoy reading all of your article post.
I wanted to write a little comment to support you.
I know this if off topic but I’m looking into starting my
own weblog and was curious what all is needed
to get setup? I’m assuming having a blog like yours would
cost a pretty penny? I’m not very internet savvy so I’m not 100% positive.
Any recommendations or advice would be greatly
appreciated. Thanks
